«Hagakure» is the most authoritative treatise dedicated to bushidō—the code of honor of the samurai. In ancient Japan, this was how the collection of rules and established principles was called, regulating the conduct and everyday life of the samurai— the warrior class that has determined the history of their country for centuries. Purity and clarity of the language, depth of thought, and utmost sincerity of personal experience characterize the work of Yamamoto Tsunetomo—a great samurai who, in his own way, tried to answer the question: “How do we live? How do we die?”
